“Some people of plain common sense do believe it for all that!” retorted Bryce. “For it's quite possible. But as I say, I'm only repeating. And of course, the rest of it follows on that. The police theory is that Collishaw witnessed Braden's death at Ransford's hands, that Ransford got to know that Collishaw knew of that, and that he therefore quietly removed Collishaw. And it is on all that that they're going, and will go. Don't ask me if I think they're right or wrong! I'm only telling you what I know so as to show you what danger Ransford is in.” Mary made no immediate answer, and Bryce sat watching her. Somehow--he was at a loss to explain it to himself--things were not going as he had expected. He had confidently believed that the girl would be frightened, scared, upset, ready to do anything that he asked or suggested. But she was plainly not frightened. And the fingers which busied themselves with the fancy-work had become steady again, and her voice had been steady all along. “Pray,” she asked suddenly, and with a little satirical inflection of voice which Brice was quick to notice, “pray, how is it that you--not a policeman, not a detective!--come to know so much of all this? Since when were you taken into the confidence of Mitchington and the mysterious person from London?” “You know as well as I do that I have been dragged into the case against my wishes,” answered Bryce almost sullenly. “I was fetched to Braden--I saw him die. It was I who found Collishaw--dead. Of course, I've been mixed up, whether I would or not, and I've had to see a good deal of the police, and naturally I've learnt things.” Mary suddenly turned on him with a flash of the eye which might have warned Bryce that he had signally failed in the main feature of his adventure. “And what have you learnt that makes you come here and tell me all this?” she exclaimed. “Do you think I'm a simpleton, Dr. Bryce? You set out by saying that Dr. Ransford is in danger from the police, and that you know more--much more than the police! what does that mean? Shall I tell you? It means that you--you!--know that the police are wrong, and that if you like you can prove to them that they are wrong! Now, then isn't that so?” “I am in possession of certain facts,” began Bryce. “I--” Mary stopped him with a look. “My turn!” she said. “You're in possession of certain facts. Now isn't it the truth that the facts you are in possession of are proof enough to you that Dr. Ransford is as innocent as I am? It's no use your trying to deceive me! Isn't that so?” “I could certainly turn the police off his track,” admitted Bryce, who was growing highly uncomfortable. “I could divert--” Mary gave him another look and dropping her needlework continued to watch him steadily.
